HENRY H. OLDS, OF NEW HAVEN, CONNECTICUT.

IMPROVEMENT IN PULP-STRA'INERS.

Specification forming part of Letters Patent No. 136,002, dated February 18, 1873.

To all Awhom it may concern:

Be it known that I, HENRY H. OLDs, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvementin Pulp-Strainers, o`fwhich the following is a specification:

My object in this invention is to provide convenient and efcient means for separating the pulp of apples, pumpkins, and similar articles from the cores, seeds, and skins; and

' it consists in a machine having a semi-cylinsponding parts.

A is the strainer, which is of any desired length, and semi-cylindrical in form, around the rim or top ot which is a frame of wood, B, to which is fitted the cap c and the hopper D. E is the revolving cylinder, of any desired forni, which is made fast to the shaft F. C is the driving-pulley on one end of the shaft. H H are the ends of the machine, to which the strainer is attached. I I a-re metallic plates on the ends, which form the bearings for the shaft, as seen in Fig. 1. J represents a series of elastic win gs or webs attached spirall y to the shaft, similar to the web of a conveyer-shaft, on the thread of a screw, so as to move the material to be strained longitudinally in the strainer, and to discharge the cores, seeds, skins, Ste., at the end opposite the hopper. K :is the discharge-aperture, to which is iitted a door or slide, so that the machine may be closed while the pulp is passing through the strainer and the rejected portion be discharged afterward. The wings J are composed of India rubber, grooved into the cylinder or fastened to it in any suitable manner; or they may be made of' wood or other material, attached to the cylinder by springs, the object being to make the wings more or less elastic. The hopper D is placed at one end of the machine, as represented in the drawing.

The apples, pumpkins, or other articles are boiled or steamed so as to be soft and readily crushed, and are fed into the machine through the hopper, where they come in Contact with the revolving wings,wl1ich crush the apples or pieces and force the pulp through the strainer. Thecores, seeds, skins, Ste., will be carried` along to the other end of the strainer, and may be discharged from time to time, as may be necessary. The wings J, by reason of their elasticity, will rub against strainer and crush the fruit and force the pulp through it.

The strainer is preferably made of brass wire-cloth, but may be made of perforated sheet metal or of slats or rods. The cylinder may be revolved by hand by means of a crank 5 but I prefer to use steam or similar motive power, and revolve the cylinder about two hundred times a minute.

The pulp thus strained is used mainly for pies, apple-butter, 8vo.

When the slow and tedious process of paring and cutting apples is considered, the saving of labor by means of this machine is immense.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The elastic wings J, cylinder E, and strainer A, combined and arranged to operate substantially as shown and described.
